HOG-SCRAPER.

Specification ofvLetters Patent. Patented June 23, 1914,

Application led June 10, 1912. Serial No. 702,769.

To all whom lif may concern Be it knoivn that I, GRANVILLE H. STALL- MAN` a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain ,new and useful Improvements in Hog- Scrapers, of which the-following is a specification.

My invention relates to improvements 1n hog scraping `and cleaning mechanism.

One of its objects is to provide mechanism whereby the hogs are regularly and automatically .fed through the mechanism and uniformly subjected to the scraping and cleaning mechanism.

' after the scraping and cleaning operation is completed, and to resume position to receive another hog.

Another ob]ect is to provide improved 'scraping and cleaning mechanism.

My invention further comprises certain details of form` combination and -arrangement, all ofwhieh will be fully set forth in the description of the accompanying drawings in which: I

Figure 1 is a side elevation of my improved niechanism; Fig. 2 is anV enlarged detail of one form of sprocket chain employed. Fig.. 3 is a top plan view. Fig. 4 is an enlarged sectional detail on line m fr of Fig. 3. Fig. 5 is a similar View on line o of Fig. 3. Fig. 6 is a sectional .detail through oneof the revolving` Scrapers, illustrating a modification.

The accompanying drawings illustrate the preferred embodiment of my invention in. which A represents al structural iron frame` into which is preferably built a tank A to the scraping and cleaning operation. l\ ounted upon the frame A is a cast frame B provided with journal bearings to support the operative mechanism.

C represents a scalding vat in` which the hogs are scalded before passing-to the scraping mechanism. The hogs are lifted one at a time from the scalding vat by means of a series of hooks 2 carried by sprocket chains 3 which are supported upon sprocket Wheels 4 carried by shaft. 5 at one end and upon sprocket Wheels 6 carried by'shaft 7 at the other end.. The shaft 5 is journaled in boxes 8 below the surface of the Water in the scalding vat carried by standards 9 from the floor of the vat. The shaft 7 is journaled in boxes 10 carried by the standards 11 of frame A. A series of angle irons12 strung upon cross rod 13 form an inclined guide- Way down which the body of the hog may roll after it has been elevated by the hooks 2 to a position above the shaft 7. In order that the hog'may roll instead of slide down the inclined bars 121.. the upper'edges of said bars are provided with notches 14. The Outside bars 12 are bolted to the frame while the intermediate bars 12 rest upon the shafts 7 and 15 and upon the edge of the vat C,be ing held in place by the cross rod13.

The shaft 15. is journaled at opposite ends, in the frame B and is provided with a series of sprocket Wheels 16. spaced eq'uidistant a part. Sprocket Wheels 17 of the same diameter are mounted upon the shaft. 18 which is also journaled to frame B and a series of sprocket chains 19 are supported upon the Wheels 16 and 17. A pair of arms 20 are pivotally supported at one end upon the shaft 18 while a* shaft. 21 is journaled in bearings 22 at the opposite or free ends of arms 20. A series of sprocket Wheels 23 are mounted upon shaft 1S alternately with the sprocket Wheels 17. Sprocket wheels 24 are mounted in linewith the Wheels 23 on the shaft. 21 and sprocket chains 25 mounted upon the respective pairs of Wheels 23 and 24. The arms 2O are normally held in the position illustrated in Fig. 1 by means of latch levers 26 pivoted at 27 to the frame and engaging pins 28 projecting from the arms 20. In this position of the arms 2O the several sprocket chains 19 and 25 form a V- shaped bed, support, or cradle for the body of the hog. and when the shaft 1S is rotated by power the chains 19 and 25 serve to drive the shafts 15 and 21, and also cause the hog to rotate with said chains as a support, or cradle.

E represents a shaft`journaled at opposite ends in frame B and having a series of scraping and cleaning members 29 and .30 mounted thereon. A shaft F is journaled atl opposite ends in bearings 31 on' the arms 20, and is provided with a similar series of scraping and cleaning members 29 and 30. A tight pulley 32 and loose pulley 33 on shaft E outside the frame B provide for the application of power at say approximately one hundred revolutions per minute to the shaft E; A pair of sprocket Wheels 34, and 35 andchain 36 serve to transmit motion from shaft E to shaft- 18 at relatively'less speed than shaft E.- The chains 19 and 25 receive motion from shaft 18 and in turn drive the shafts 15 and 21. The shaft 7 is driven from shaft 15 by lmeans of sprocket wheels 37 and 38 and chain 39. Loosely mounted upon the shaft 18 is a sleeve upon whiehare' rigidly mounted two sprocket wheels 40 and 40', which are driven from shaft E by means of a chain 42 from sprocket wheel 41 on shaft E while a chain v 43 driven by the wheel 40 engages a sprocket .wheel 43 on shaft F and serves to drive shaft F at the same speed as shaft E, and irrespective of the position of the arms 20.

A shaft 44 journaled at opposite ends to frame B receives relatively slow motion from shaft 15 by means of a chain 45 running over the sprocket wheels 46 and 47. Sprocket wheels 48 on shaft 44 serve by means of sprocket chains 49 to drive at a still slower rate the sprocket wheels 50 which are mounted upon stud shafts carried by the frame 13. The wheels 50 are armed with crank pins 450 which at 'regular intervals engage the upwardly projecting arms 51 of the latch members 26 to trip said latch members to release the arms 20, which under the weight of the hog resting'upon the chains 25 assume a substantially horizontal position whereupon the chains 25 feed the hog over the sprocket wheels 24 and onto atable or conveyer 52 ready to be inspected and then carried away on the overhead track 53. Immediately, after the chains 25 and arms20 are relieved of the weight of the hog, the counterweights 54 attached by cables 55 passing over rollers 56 on frame B cause the arms 20 to resume the position illustrated in Fi 1, in position to receive another hog.

V uring the operation o f cleaning warm Water supplied by pipe 57 is sprayed upon the hog and the water, bristles and solid matter are caught upon an inclined tray 58 and conducted to a perforated trough 59 where the water is drained into tank A and a conveyer 60 driven by a chain 61 from shaft 18 feeds the -bristles or Aother solid matter' out at one end of the trough 59. The water from tank A may be returned to pipe 57 by means of a rotary pump 62 driven by belt 63 from pulley 64 on shaft E, or fresh water may be continuously supplied to pipe 57 and used only once and then wasted by directing it into a sewer orlike receptacle.

In order to thoroughly scrape and clean all parts of the hogs, I preferably provide scraping members 30 of relatively less diam* eter opposite the central and nearly cylindrical portion of the body and scraping members 29 of relatively greater diameter opposite the respective ends of the body. The scraping members may all be alike except as to diameter if desired, but I prefer to otherwise modify the scraping members operating upon the ends` of the body as compared with those operating upon the central portion of the body. In Figs.4 and 6, are illustrated the scraping and cleaning members preferably employed opposite the ends of the body, which comprise hubs 65 rigidly attached to vthe shafts E and F, said hubs having grooves 66 in which are seated strong and comparatively stiff strips 67 of canvas belting or similar material said strips being held in place upon the hubs 65 by means of clamping bars 68 bolted to the hubs.

are preferably united together and so arranged as to mutually support each other, and on the side facing the direction of rotation are provided a series of metal scrapers f formedof short sections of angle iron firmly secured to the strips 67. Two series of strips 67 are preferably secured in staggered relationto one hub, and the hubs set in staggered relation upon t-he respective shafts E and F. The distance between the shafts E and F is such that the free ends of the strips 67 of the opposed scraping members very closely approach each other, but without liability of touching. In Fig. 1 the dotted circles 68 approximately represent the line of travel of the peripheries of Scrapers 29, while the dotted circles l69 approximately represent the line of travel of the peripheriesof the Scrapers 30, said scrapers' being otherwise omitted from Fig. 1. The strips 67 may be projected radially at right angles to the axis vof the shaft as indicated in Figs." 2 and 3, or may if desired, be set diagonally with reference to the shaftaxis as illustrated in Fi 6 in which strips 67 correspond to the strips 67 of Fig.. 3, being held upon the hub 70 by means o-f clamp members 71 and screws 72. The diagonal arrangement Fig. 6 enables the strips 67 to more readily engage and clean the tapered or rounded ends of the body. The series of Scrapers f on the respective strips 67 enable both ends and also thelimbs to be eifectually scrapedand cleaned.

The Scrapers `30 comprise peripheral bands 75 of comparatively stiff but flexible canvas belting or'similar material supported from thehubs 76 by means of Vspokes .77 composed of substantially the same material as the peripheral bands 75, to which they are united by rivets. Clamping members 78 bolted to-the hubs serve to lock the spokes` 77 to the hubs. A series of Scrapers 79 con- TheA outwardly projecting ends of the strips 67 sistin'g of short metal angle bars are- Secured Shorter sections set in staggered relation. nd'er the' pressure exerted by the body of the hog, the bands 75 and spokes are free to yield or partiallycollapse, while the chainsv 19' and 2'5 prevent the body coming in contact with the hubs 7 6, hence the scrapers 79* are' successively drawn With' a yielding pressure' across the central portion of the slowly' revolving body, and serve to scrape andi cleari-v the same. In practice a body will make approximately three revolutions Supported upon the cha-ins 19 and 25 a-ndexposed to the action of the revolving scrapers, and is vthen fed away to the table or conveyer 52.

The movements of the hooks 2 and the pins 50 which: release the latches 26 are so timed as' to automatically deliver another body onto the chains 19 and 25 as Soon as the arms 20 have returned and been engaged by the latch members 26. In order to facilitate rotating the body and feeding it from the machine, I preferably p-rovide the chains 19 and 25ywith attachment lugs or teeth 80 as indicated in Fig. 2.

The mechanism herein illustrated and described is capable of considerable modification without-departing from the principle of my invention.
